Description
Technical Field
[0001] The present invention relates to the technical field of autoclave material forming, and in particular to a method, device, equipment and medium for predicting the flow field and temperature field of an autoclave. Background Art
[0002] An autoclave is a specialized pressure vessel capable of withstanding and regulating a wide range of temperatures and pressures. The autoclave molding process offers advantages such as uniform pressure and air temperature within the vessel, a wide range of applications, and a stable and reliable molding process, ensuring consistent component quality. Consequently, autoclave molding technology is widely used in the aerospace industry, particularly for the molding of large, complex-surface skins, panels, and hulls.
[0003] Conventional technology achieves uniform temperature in the autoclave's flow field by compensating the autoclave's low-temperature zone and using a blower to increase the flow rate of the fluid in this low-temperature zone, accelerating heat exchange between the fluid and the outside world. Alternatively, a function is used to convert the time-varying pressure inside the autoclave into a time-varying density to improve the accuracy of temperature field simulation.
[0004] However, in the above-mentioned prior art, the wind speed of the flow field inside the autoclave is defined as a fixed value, without considering the impact of different wind speeds at different locations on the temperature. In actual applications, due to the influence of the autoclave's own air outlet method and structure, the gas inside the autoclave does not flow completely uniformly at the same flow rate. There are even "dead zones" (i.e., areas with poor wind speed distribution) inside the autoclave. Therefore, in order to achieve a more ideal numerical simulation effect, it is urgent to accurately predict the flow field inside the autoclave. Summary of the Invention

[0041] Embodiment one
[0042] Figure 1a is a flow chart of a flow field prediction method of a hot press tank according to an embodiment one of the present application. The present embodiment can be applicable to the case of accurately predicting the wind speed distribution in the hot press tank. The method can be executed by a flow field prediction device of the hot press tank. The flow field prediction device of the hot press tank can be realized in the form of hardware and / or software. The flow field prediction device of the hot press tank can be configured in an electronic device. The electronic device can be a computer, or a simulation controller, etc. As shown in Figure 1a , the method comprises:
[0043] Step 110, measuring the wind speed of at least two transverse sections of the hot press tank by a wind speed detection device arranged in the hot press tank to obtain the wind speed measurement results of each transverse section.
[0044] For example, the size of the hot press tank is (diameter 5.5 meters, length 20 meters). In the hot press tank, the temperature of the region in the hot press tank can be raised or lowered by heating or cooling the gas in the tank. Due to the hot air circulation heating characteristics of the hot press tank, the hot distribution in the hot press tank is often large. Therefore, in the embodiment of the present application, the flow field prediction of the hot press tank can be determined first, and then the temperature field prediction of the hot press tank is performed. While the hot press tank is heated, the working pressure in the tank will also gradually increase, and finally the pressure in the tank remains unchanged. Therefore, the flow field and temperature field of the hot press tank are crucial to the molding of the component, and accurate flow field and temperature field prediction of the hot press tank is required.
[0045] Figure 1b is a hot press tank structure design and air circulation characteristic diagram according to an embodiment one of the present application. As shown in Figure 1bAs shown, the gas medium in the tank flows to the tank door 106 along the air duct 102 around the autoclave via the fan 101, and under the convergence effect of the tank door 106, the gas medium flows through the tank body to realize heat transfer to the mold 103 and the component 104. Among them, the mold 103 and the component 104 can be placed on the wall surface 105 of the autoclave, and the molding design is carried out under uniform temperature and pressure. The fan 101, the heating device 108 and the cooling device 107 are arranged between the inner and outer cylinders of the autoclave, and by adjusting the heating device 108 or the cooling device 107, the heating or cooling of the gas medium can be realized, and then the heating or cooling of the area inside the autoclave can be realized.
[0046] In the embodiment of the present application, a wind speed detection device can be arranged in the autoclave to measure the wind speed, and a plurality of wind speed measurement results of the transverse sections are obtained. The wind speed detection device can include a wind speed measuring instrument. In order to improve the accuracy of the wind speed distribution measurement, a plurality of wind speed measuring instruments can be arranged in a transverse section to obtain the wind speed of a plurality of test points in the same transverse section, so as to obtain the wind speed distribution function corresponding to the transverse section.
[0047] For example, the transverse section can be selected at the inlet surface of the autoclave, 3 meters, 5 meters or 10 meters away from the tank opening, and the wind speed detection device is arranged to measure the wind speed of the corresponding transverse section.
[0048] Step 120, determining the wind speed distribution function of the autoclave according to the wind speed measurement result of the first transverse section.
[0049] For example, the first transverse section can be the inlet surface of the autoclave. The wind speed distribution function of the autoclave can be obtained by fitting the wind speed measurement result of the inlet surface of the autoclave. The fitting method can be a numerical sequence analysis algorithm, and the embodiment of the present application does not make specific limitation.
[0050] Step 130, according to the model simulation file of the autoclave and the wind speed distribution function, performing steady-state calculation on the autoclave under the preset flow field parameters of the autoclave to obtain the flow field distribution result of the autoclave.
[0051] The model simulation file of the autoclave can be obtained by geometric modeling of the autoclave through engineering simulation software to obtain a geometric model, and then performing finite element network division on the geometric model to obtain a grid file. Through the geometric modeling and grid division of the autoclave, the numerical simulation of the flow field and the temperature field of the autoclave can be facilitated, and the efficiency and accuracy of the numerical simulation can be improved.
[0052] The preset flow field parameters of the autoclave can include properties and boundary conditions of the autoclave. For example, the properties of the autoclave can include a fluid state model in the autoclave, a gas medium, and a wall material. For example, the fluid state model in the autoclave is determined according to the Reynolds number, and when the fluid state in the autoclave is turbulent flow, a suitable turbulent flow model Standard k-ε can be selected. The gas medium in the autoclave is nitrogen. The wall material is steel. The boundary conditions can include inlet boundary conditions and outlet boundary conditions. The inlet boundary condition can be a velocity inlet boundary condition. For example, the velocity inlet boundary can be set as a self-defined wind speed distribution function, such as a wind speed distribution function measured and fitted at the inlet face of the autoclave. The outlet boundary condition can be a pressure outlet boundary condition.
[0053] The steady-state calculation of the finite element model of the autoclave can be performed according to the numerical values of the preset flow field parameters of the autoclave by engineering simulation such as computational fluid dynamics simulation software, and the flow field distribution result of the autoclave can be obtained.
[0054] In step 140, the wind speed measurement results of the second transverse section are compared with the flow field distribution result.
[0055] The wind speed distribution can be different at different transverse sections. When comparing the wind speed, the wind speed measurement results at the same transverse section position can be compared with the flow field distribution result. For example, the wind speed measurement results of the transverse section 3m away from the inlet face are compared with the flow field distribution result to ensure the rationality of the comparison.
[0056] In step 150, when the wind speed comparison result satisfies the flow field prediction accuracy, the preset flow field parameters and the wind speed distribution function are taken as the flow field prediction result of the autoclave.
[0057] For example, when the wind speed measurement results of each transverse section and the flow field distribution result of the corresponding transverse section have a deviation within 5%, it is determined that the wind speed comparison result satisfies the flow field prediction accuracy.
[0058] When the wind speed comparison result satisfies the flow field prediction accuracy, the preset flow field parameters and the wind speed distribution function can be directly taken as the flow field prediction result of the autoclave. Thus, the accurate simulation of the flow field of the autoclave is realized.
[0059] In step 160, when the wind speed comparison result does not satisfy the flow field prediction accuracy, the preset flow field parameters are adjusted, and the process returns to step 130.
[0060] By repeatedly adjusting the preset flow field parameters when the wind speed comparison result does not satisfy the flow field prediction accuracy, so that the wind speed comparison result satisfies the flow field prediction accuracy, the accuracy of the simulation of the wind speed distribution of the autoclave can be ensured.
[0061] In actual application, when the autoclave is in the preset flow field parameters corresponding to the flow field prediction accuracy, the wind speed distribution of each transverse section can be directly predicted through the wind speed distribution function, ensuring the accuracy of the wind speed distribution prediction, without the need to set a wind speed detection device in the autoclave, improving the convenience of the autoclave flow field prediction. At the same time, the simulation error caused by ignoring the uneven wind speed distribution in the autoclave can be reduced, the accuracy of the flow field is improved, and then the accurate temperature field prediction is facilitated.
[0062] The technical scheme of the embodiment of the present application measures the wind speed of at least two transverse sections of the autoclave through the wind speed detection device arranged in the autoclave, and obtains the wind speed measurement results of each transverse section; determines the wind speed distribution function of the autoclave according to the wind speed measurement results of the first transverse section; performs steady-state calculation on the autoclave under the preset flow field parameters of the autoclave according to the model simulation file of the autoclave and the wind speed distribution function, and obtains the flow field distribution results of the autoclave; compares the wind speed measurement results of the second transverse section with the flow field distribution results; when the wind speed comparison results meet the flow field prediction accuracy, the preset flow field parameters and the wind speed distribution function are taken as the flow field prediction results of the autoclave, solving the flow field prediction problem of the autoclave. By arranging the wind speed detection device in the autoclave to detect the wind speed in the autoclave, the preset flow field parameters of the autoclave are adjusted, the accurate simulation of the wind speed distribution in the autoclave can be realized, the wind speed distribution function of the autoclave flow field is obtained, the wind speed distribution in the autoclave is accurately known, and then on the basis of accurate autoclave flow field simulation, the accurate temperature field prediction of the autoclave is facilitated.
[0063] In order to improve the accuracy of the wind speed measurement in the autoclave, the wind speed detection device arranged in the autoclave is specifically described as follows.
[0064] On the basis of the above-mentioned embodiment, optionally, the wind speed detection device comprises a data acquisition assembly, at least one support assembly, and at least one wind speed measuring instrument; wherein the support assembly is arranged on at least two transverse sections of the autoclave; the wind speed measuring instrument is arranged on the support assembly, and the wind speed measuring instrument is arranged on different wind speed test positions of the transverse sections in the autoclave through the support assembly; each wind speed measuring instrument is connected with the data acquisition assembly, and the data acquisition assembly records the wind speed measuring instrument data at the wind speed test position of the corresponding transverse section.
[0065] Optionally, the support assembly extends in the vertical direction in the transverse section; the support assemblies in the same transverse section are arranged at intervals, and at least one wind speed measuring instrument is connected to each support assembly.
[0066] Figure 1c is a structural schematic view of a wind speed detection device according to the embodiment one of the present application. As shown in Figure 1cAs shown, a working platform is provided on the bottom wall of the autoclave. The wind speed detection device in the autoclave includes a data acquisition component 201, multiple anemometers 202, and multiple support components 203. The anemometers 202 are mounted on the support components 203, which are used to position the anemometers 202 at different points inside the autoclave.
[0067] Optionally, the support assembly 203 is arranged on at least one transverse section 200 of the autoclave and extends in the vertical direction; the support assemblies 203 on the same transverse section 200 are arranged at intervals, and each support assembly 203 is connected to at least one anemometer 202 .
[0068] Multiple anemometers 202 are spaced apart on the transverse section 200 through multiple support assemblies 203 , so that multiple anemometers 202 are arranged in the transverse section 200 in both horizontal and vertical directions, and can respectively detect wind speeds at different positions on the transverse section 200 .
[0069] The data acquisition component 201 is mounted on a work platform 204 and is in communication with the anemometer 202. It collects and stores data detected by the anemometer 202. After detection, the data can be exported and mathematically analyzed to obtain a wind speed distribution function, thereby determining the wind speed distribution pattern within the autoclave's transverse cross-section 200. During simulations, this function is used as a boundary condition for wind speed, reducing simulation errors and improving the accuracy of the results.
[0070] Each anemometer 202 is connected to the data acquisition assembly 201 via a wire. The anemometer 202 can be a wind speed transmitter. The anemometer 202 can have a measuring range of 5 m / s. In other embodiments, the measuring range of the anemometer 202 is selected based on the wind speed parameters within the autoclave.
[0071] In a specific application, if the wind speed distribution of the autoclave is left-right asymmetric in the transverse section, the wind speed of the entire tank surface can be detected, that is, the support assembly and the wind speed measuring instrument are set on the entire tank surface.
[0072] For example, Figure 1b The autoclave's gas outlet can be bilaterally symmetrical, all-around. In this case, simply installing a support assembly and anemometer on one side of the longitudinal centerline of the transverse cross-section suffices to obtain wind speed distribution across the entire tank surface. This reduces the number of support assemblies and anemometers required, while ensuring reliable wind speed measurement.
[0073] The length of the support assembly 203 at the longitudinal center line is the longest, and the length of the support assembly 203 away from the longitudinal center line decreases successively.
[0074] As shown in the drawings, Figure 1c As shown in the drawings, when the wind speed distribution is left-right symmetrical in the transverse section, three support assemblies 203 can be arranged on one side of the longitudinal center line of the transverse section. The number of the support assemblies 203 can be adjusted according to actual conditions.
[0075] Optionally, the support assembly 203 comprises a connecting frame 2031 and a base 2032, the base 2032 is arranged on the working platform 204, and the connecting frame 2031 is arranged above the base 2032 and is inserted with the base 2032. During installation, the connecting frame 2031 and the base 2032 can be fixed by simply inserting the connecting frame 2031 with the base 2032, which facilitates quick installation and disassembly of the support assembly 203. One wind speed measuring instrument 202 is connected to each connecting frame 2031, so that the wind speed measuring instruments 202 are arranged in multiple in the horizontal direction in the transverse section, and the wind speed at multiple positions in the horizontal direction in the transverse section can be measured.
[0076] Further, Figure 1d is a structural schematic view of a base in a support assembly according to an embodiment of the present application. As shown in the drawings, Figure 1c and Figure 1d As shown in the drawings, the base 2032 comprises a bottom plate 20321 and a fixed column 20322, the bottom plate 20321 is arranged on the working platform 204, and the fixed column 20322 is connected to the bottom plate 20321 vertically, the connecting frame 2031 comprises a sleeve and a fixed plate, the sleeve is connected to the fixed plate vertically, the fixed column 20322 is inserted with the sleeve, and the wind speed measuring instrument 202 is connected to the sleeve.
[0077] As shown in the drawings, Figure 1c and Figure 1d As shown in the drawings, the bottom plate 20321 is placed on the working platform 204, and the fixed column 20322 is arranged in three, which can improve the connection strength of the connecting frame 2031 and the base 2032. The three fixed columns 20322 are arranged in a regular triangle, which improves the stability of the connection of the connecting frame 2031 and the base 2032. One end of the fixed column 20322 is fixedly connected to the side of the bottom plate 20321 away from the working platform 204, and the other end extends upward. The fixed column 20322 and the bottom plate 20321 can be fixed by welding or bolt connection, which is not limited in the embodiment of the present application. The sleeve is arranged in three, and the sleeve corresponds to the fixed column 20322 one by one. One end of the sleeve is fixedly connected to the side of the fixed plate facing the bottom plate 20321, and the other end extends downward. The inner diameter of the sleeve is greater than or equal to the outer diameter of the fixed column 20322, and the fixed column 20322 is inserted into the sleeve to fix the sleeve and the fixed column 20322. The sleeve and the fixed plate can be fixed by welding or bolt connection, which is not limited in the embodiment. In another embodiment, the sleeve can be connected to the base 2032, and the fixed column 20322 can be connected to the fixed plate, and the fixed column 20322 is inserted with the sleeve.
[0078] Optionally, as Figure 1c The support assembly 203 further comprises a positioning frame 2033 connected to one side of the connecting frame 2031 away from the base 2032, and a wind speed measuring instrument 202 is connected to the positioning frame 2033. By arranging the positioning frame 2033, multiple wind speed measuring instruments 202 can be arranged in the vertical direction, so as to measure the wind speed at multiple positions in the vertical direction in the horizontal cross section.
[0079] Further, multiple positioning frames 2033 are arranged, and the multiple positioning frames 2033 are arranged in the vertical direction in sequence, and two adjacent positioning frames 2033 are detachably connected, so as to facilitate the installation, disassembly and taking of the positioning frames 2033.

By arranging multiple positioning frames 2033, the number of wind speed measuring instruments 202 arranged in the vertical direction can be increased, and the accuracy of the detection result can be improved.
[0080] Specifically, as Figure 1c shown, the support assembly 203 arranged on the longitudinal center line of the horizontal cross section is provided with four positioning frames 2033. The four positioning frames 2033 are arranged in the vertical direction in sequence and connected by bolts. One end of the lowermost positioning frame 2033 away from the base 2032 is connected to one side of the connecting frame 2031 away from the base 2032 by a bolt. The support assembly 203 close to the longitudinal center line is provided with one positioning frame 2033. The length of the positioning frame 2033 in the vertical direction ranges from 0.8m to 1.5m, and in the embodiment, the length of the positioning frame 2033 in the vertical direction is 1m.

The first positioning plate 20331 and the second positioning plate 20332 are arranged in a vertical direction, and the plurality of connecting rods 20333 are arranged in a horizontal direction. One end of the connecting rod 20333 is connected to the first positioning plate 20331, and the other end is connected to the second positioning plate 20332. The side of the first positioning plate 20331 opposite to the connecting rod 20333 is connected to the side of the connecting frame 2031 opposite to the base 2032. The first positioning plate 20331 facilitates the connection of the positioning frame 2033 and the connecting frame 2031, and can increase the contact area of the positioning frame 2033 and the connecting frame 2031, and improve the connection strength of the positioning frame 2033 and the connecting frame 2031.

The wind speed measuring instrument 202 is connected to the connecting rod 20333.
[0082] Specifically, three connecting rods 20333 are provided, which can improve the strength of the positioning frame 2033. The three connecting rods 20333 are arranged in a regular triangle, which improves the stability of the connection of the connecting rod 20333 and the first positioning plate 20331 and the second positioning plate 20332. The connecting rod 20333 is welded to the first positioning plate 20331 and the second positioning plate 20332. The first positioning plate 20331 of one of the two adjacent positioning frames 2033 is connected to the second positioning plate 20332 of the other positioning frame 2033 by a bolt. The first positioning plate 20331 of the lowermost positioning frame 2033 is connected to the fixed plate by a bolt.

[0096] Figure 2a It is a flow chart of a temperature field prediction method of an autoclave according to the second embodiment of the present application. The present embodiment can be applicable to the case of accurately predicting the temperature change in the autoclave. The method can be executed by an autoclave temperature field prediction device. The autoclave temperature field prediction device can be realized in the form of hardware and / or software. The autoclave temperature field prediction device can be configured in an electronic device. The electronic device can be a computer, or a simulation controller, etc. As shown in the figure, the method comprises the following steps. Figure 2a
[0097] Step 210, the wind speed of the autoclave at at least two transverse sections is measured by the wind speed detection device arranged in the autoclave, and the wind speed measurement results of each transverse section are obtained.
[0098] Optionally, the wind speed detection device comprises a data acquisition assembly, at least one supporting assembly, and at least one wind speed measuring instrument. The supporting assembly is arranged at at least two transverse sections of the autoclave. The wind speed measuring instrument is arranged on the supporting assembly, and is arranged at different wind speed test positions of the transverse sections in the autoclave through the supporting assembly. Each wind speed measuring instrument is connected with the data acquisition assembly, and the data of the wind speed measuring instrument at the wind speed test position of the corresponding transverse section is recorded through the data acquisition assembly.
[0099] Optionally, the supporting assembly extends in the vertical direction in the transverse section. The supporting assemblies in the same transverse section are arranged at intervals, and at least one wind speed measuring instrument is connected to each supporting assembly.
[0100] Specifically, the specific structure of the wind speed detection device can be as shown in Figure 1c 、 Figure 1d and Figure 1e , and is obtained through the above corresponding explanation, which will not be repeated here.
[0101] Step 220, the wind speed distribution function of the autoclave is determined according to the wind speed measurement results of the first transverse section.
[0102] Step 230, according to the model simulation file of the autoclave and the wind speed distribution function, a steady-state calculation is performed on the autoclave under the preset flow field parameters of the autoclave to obtain the flow field distribution result of the autoclave.
[0103] Step 240, the wind speed measurement result of the second transverse section is compared with the flow field distribution result.
[0104] Step 250, when the wind speed comparison result meets the flow field prediction accuracy, the preset flow field parameters and the wind speed distribution function are taken as the flow field prediction result of the autoclave, and step 270 is performed.
[0105] Step 260, when the wind speed comparison result does not meet the flow field prediction accuracy, the preset flow field parameters are adjusted, and step 230 is returned.
[0106] Step 270, temperature data of at least one temperature test position inside the autoclave is collected by a temperature detection device inside the autoclave.
[0107] The temperature detection device can be a temperature sensor or a thermocouple. Figure 2b is a position distribution diagram of a temperature detection device in an autoclave according to an embodiment two of the present application. Figure 2b The black dots in indicate the positions of the temperature detection devices. As shown in Figure 2b , the temperature detection devices can be arranged on at least one transverse section of the autoclave. Specifically, the temperature detection devices can be arranged on the mouth surface, the middle surface and the tail surface of the autoclave as shown in Figure 2b . On one transverse section, at least one temperature detection device can be arranged. For example, on the mouth surface, the middle surface and the tail surface, temperature detection devices can be arranged on the center point of the surface, the upper end of the surface, the left side of the surface and the right side of the surface. Temperature data of at least one measurement point inside the autoclave can be collected by the temperature detection devices inside the autoclave.
[0108] Step 280, according to the model simulation file, the preset flow field parameters, the wind speed distribution function and the preset thermal property parameter value, a transient calculation is performed on the autoclave to obtain the temperature field distribution result in the autoclave.
[0109] The preset thermal property parameter value can be a parameter related to temperature, such as the gas medium in the autoclave and the wall material. For example, the gas medium in the autoclave is nitrogen. The wall material can be a thermal insulation wall. The thermal property parameters can include but are not limited to specific heat capacity and thermal conductivity. Table 1 is an exemplary thermal property parameter setting value. The density and velocity of nitrogen can be set by a user-defined function (UDF) at the inlet boundary condition of the autoclave.
[0110] Table 1
[0111] Material Specific heat capacity / (kJ / (kg K)) Thermal conductivity / (W / (m K)) Density / (kg / m3) Nitrogen 1.0406 0.0242 User-defined function Aluminum 16.29 502.48 7930
[0112] The simulation software of engineering simulation such as computational fluid dynamics can simulate the temperature field distribution result in the autoclave according to the model simulation file, the preset flow field parameter, the wind speed distribution function and the preset thermal physical parameter value. When performing the transient calculation, the model simulation file can be calculated according to the given condition of the inlet surface of the autoclave, that is, the thermal physical parameter value, in combination with the wind speed distribution function, to obtain the temperature change of each position in the autoclave with time under the wind speed distribution function, that is, the temperature field distribution result in the autoclave.
[0113] Step 290, compare the temperature data of each temperature test position with the temperature field distribution result of the corresponding position.
[0114] When performing the temperature comparison, the temperature data of the same position in the same transverse section can be compared with the temperature field distribution result of the corresponding position.
[0115] Step 2100, when the temperature comparison result satisfies the temperature prediction accuracy, the temperature field distribution result is taken as the temperature field prediction result of the autoclave under the preset flow field parameter, the wind speed distribution function and the preset thermal physical parameter value.
[0116] The temperature prediction accuracy can be that the temperature difference is within the preset temperature range. The preset range can be a value within the interval [-5, 5]. For example, when the temperature difference is less than or equal to 2.8 degrees Celsius, it is determined that the temperature comparison result satisfies the temperature prediction accuracy. When the temperature comparison result satisfies the temperature prediction accuracy, the temperature field distribution result can be taken as the temperature field prediction mode of the autoclave under the wind speed distribution function. In actual application, when the component forming design of the autoclave is performed, the temperature field distribution result can be directly used to predict the temperature inside the autoclave under the model simulation file, the preset flow field parameter, the wind speed distribution function and the preset thermal physical parameter value, without the need to set temperature detection devices and wind speed detection devices inside the autoclave, so that the accuracy and convenience of the temperature field prediction can be improved.
[0117] Step 2110, when the temperature comparison result does not satisfy the temperature prediction accuracy, the preset thermal physical parameter is adjusted and set, and the step 280 is returned.
[0118] When the temperature comparison result does not satisfy the temperature prediction accuracy, it indicates that the current simulation result deviates from the actual measured result, and the temperature field inside the autoclave cannot be accurately measured. Therefore, when the temperature comparison result does not satisfy the temperature prediction accuracy, the preset thermal physical property parameters are adjusted again, and the autoclave is re-calculated in the wind speed distribution function by using the preset thermal physical property parameter value to obtain the temperature field distribution result. Iterative execution is performed until the temperature field distribution result and the temperature data comparison result of each point position satisfy the prediction accuracy, and the temperature field distribution result is taken as the temperature field prediction mode of the autoclave under the wind speed distribution function.

Figure 2d is a tank middle surface temperature comparison result schematic diagram of a hot press provided according to Embodiment Two of the present application. Figure 2e is a tank tail surface temperature comparison result schematic diagram of a hot press provided according to Embodiment Two of the present application. For example, the temperature data measured by the temperature detection device at the center point of the tank opening surface, the tank middle surface and the tank tail surface are compared with the temperature of the corresponding point position in the temperature field distribution result obtained by simulation. According to the temperature-time curve shown in Figure 2c , Figure 2d and Figure 2e , it can be known that the temperature field distribution result is highly close to the temperature-time curve of the measured temperature data, thereby verifying the accuracy of the present application in predicting the temperature field of the hot press.

Under the preset flow field parameters of the autoclave, the autoclave is subjected to steady-state calculation to obtain the flow field distribution result of the autoclave; when the wind speed comparison result meets the flow field prediction accuracy, the preset flow field parameters and the wind speed distribution function are used as the flow field prediction result of the autoclave; the temperature data of at least one temperature test position inside the autoclave is collected through the temperature detection device inside the autoclave; according to the model simulation file, the preset flow field parameters, the wind speed distribution function, the flow field distribution result of the autoclave is obtained; function and preset thermophysical parameter values, perform transient calculation on the autoclave, and obtain the temperature field distribution result inside the autoclave; compare the temperature data of each temperature test position with the temperature field distribution result of the corresponding position; when the temperature comparison result does not meet the temperature prediction accuracy, adjust the preset thermophysical parameter and return to the step of performing transient calculation on the autoclave according to the model simulation file, preset flow field parameters, wind speed distribution function and preset thermophysical parameter values to obtain the temperature field distribution result inside the autoclave; when the temperature comparison result meets the temperature prediction accuracy, use the temperature field distribution result as the temperature field prediction result of the autoclave under the preset flow field parameters, wind speed distribution function and preset thermophysical parameter values, solve the flow field and temperature field prediction problem of the autoclave, improve the accuracy of temperature prediction by performing temperature prediction under the wind speed distribution function, determine the final prediction method by comparing the temperature prediction result with the measurement result, and directly adopt the accurate temperature prediction method in subsequent applications without setting the wind speed detection device and the temperature detection device, thereby improving the convenience of the flow field and temperature field prediction of the autoclave.
